MUST READ: cascade temperature controller issue

dear cascade users
all this condensation/cold chuck mess happening on the cascade chuck
is unacceptable. It is hurting the CV and IV measurments seriously.
1. Please plan a 30 min overhead when using temperature controller.
2. when you come to system, the chuck should not be cold. please feel
the chuck with a gloved hand. If it is cold or condensing, kill the
previous user :). We have already suspended one bad user.
3. Nitrogen flows all the time when temperature controller (high or
low T) is under use.
4. So you go to desired temperature (low/high) and measure devices.
Then after finishing the measurement, you go to 110C and stay there
for 10 min to boil off any condensation. Then you go to 40C (VERY
IMPORTANT, THIS IS NOT 27C or RT - THIS IS WHERE EVERYONE IS MESSING
UP) and rest for 10 min. Then turn off the temperature controller. let
nitrogen flow for sufficient time (>10 min).
If you ramp down to 27C, the temperature chiller starts and cools the
ambient - causing condensation...which is BAD.
5. Record all temperature ramps on the log sheets
happy measuring and lets be responsible users.
